Toy building element with transverasal openings

Abstract

A toy building element comprising one or more first beam-like parts ( 23, 24 ) with a plane internal face and an external face, and one or more other beam-like parts ( 21, 22 ) with a plane internal face and an external face. The beam-like parts are assembled in at least one corner whereby two internal faces are caused to form an angle of less than 180° relative to each other. At least the first beam-like part ( 23, 24 ) is/are provided with an opening ( 7 ) that extends transversally thereto from the external face to the internal face, and the opening ( 7 ) is arranged so far towards the corner that the plane for the face of the plane internal face ( 4 ) of the second beam-like part ( 21, 22 ) intersects the opening in the plane for the face of the plane internal face ( 3 ) of the first beam-like part ( 23, 24 ). The plane internal face ( 4 ) of the second beam-like part ( 21, 22 ) is interrupted at a distance from the opening ( 7 ) whereby a clearance is provided around the opening ( 7 ) on the internal face of the first beam-like part.

What is claimed is:  
     
       1. A toy building element comprising a first beam part ( 1 ;  23 ,  24 ;  33 ,  34 ) with a plane internal face ( 3 ) and an external face ( 5 ), and a second beam part ( 2 ;  21 ,  22 ;  31 ,  32 ) with a plane internal face ( 4 ) and an external face ( 6 ), said beam parts being assembled in a corner whereby the two internal faces ( 3 ,  4 ) are caused to form an angle of less than 180° relative to each other, wherein at least the first beam part ( 1 ; 23 ,  24 ;  33 ,  34 ) is provided with an opening ( 7 ) that extends transversally thereto from the external face ( 5 ) to the internal face ( 3 ), characterised in that the opening ( 7 ) is arranged so far towards the corner that the plane for the face of the plane internal face ( 4 ) of the second beam part ( 2 ;  21 ,  22 ;  31 ,  32 ) intersects the opening in the plane for the face of the plane internal face ( 3 ) of the first beam-like part ( 1 ;  23 ,  24 ;  33 ,  34 ); and that the plane internal face ( 4 ) of the second beam part ( 2 ;  21 ,  22 ;  31 ,  32 ) is interrupted at a distance from the opening ( 7 ), whereby a clearance is accomplished around the opening ( 7 ) of the internal face ( 3 ) of the first beam part. 
     
     
       2. A toy building element according to  claim 1 , characterised in that the opening ( 7 ) has a circular cross section; and that an indentation ( 8 ) is provided around the opening ( 7 ) in both the external face ( 5 ) and the internal face ( 3 ) of the first beam part. 
     
     
       3. A toy building element according to  claim 2 , characterised in that the indentation ( 8 ) in the internal face ( 3 ) extends circularly around the first half of the opening ( 7 ) and outwards towards the edge in a width and depth that correspond to the width and depth of the circular part of the indentation ( 8 ). 
     
     
       4. A toy building element according to  claim 1 , characterised in that the plane internal face ( 4 ) of the second beam part ( 2 ;  21 ,  22 ;  31 ,  32 ) is extended by an arched part ( 10 ) that arches inwards and abuts on the plane internal face ( 3 ) of the first beam part ( 3 ) within the opening ( 7 ). 
     
     
       5. A toy building element according to  claim 1 , characterised in that the toy building element comprises four beam parts ( 21 ,  22 ,  23 ,  24 ;  31 ,  32 ,  33 ,  34 ) that combine to form a closed frame; and that openings ( 7 ) are provided in all of the beam parts. 
     
     
       6. A toy building element according to  claim 1 , characterised in that the toy building element is provided with upwardly extending coupling studs ( 9 ) and with downwardly extending skirts and pins ( 26 ) that form coupling means that are complementary with the upwardly extending coupling studs ( 9 ).
